Our Analysis and Test Results
One of the highest performing boots in our tests, the Lange RX 110 LV is a boot for ladies who want a highly responsive, go anywhere, ski boot with more comfort than a race version. We tested these boots during storms, in freezing temperatures and on sunny days. We skied everything from hardpacked groomers to soft powder, steeps, and bumps, and they never let us down.
Unlike their predecessor, these boots no longer need you to hammer against them to convince them to perform. Instead, try finessing this boot. It responds much better. The consensus from our testers was that the RX 110 LV feels very responsive and energetic. Transferring power from the front of the boot to the tip of the ski is seamless.
Lange, like so many other companies, constructed this boot with a newer, more rigid and elastic (or snappy) plastic. This makes the boot feel noticeably quicker, and increases flex control. All this fancy stuff means is that, when you press forward with your shin, the boot gives you an equal pushback, making it easier to find rhythm and speed control.
If you are used to a stiffer feeling boot, this may not be the boot for you. We agreed that the race-inspired look is mostly that. Looks can be deceiving because this boot skis more like the Nordica Speedmachine 105, an excellent intermediate to advanced boot. Note that our 150lb and taller testers felt like the boot collapsed more quickly than the Nordica Speedmachine 105. The RX 110's predecessor skied more like the hard-charging Tecnica Mach1. This is no longer the case. One of our testers skis the Lange RS 110 daily and commented that the RX feels like it has a completely different flex.
This is not to take anything away from the boot. We still consider its precision and responsiveness outstanding. It's just that, the newer RX 110 LV now appeals to a much larger range of women, not just the ex-racers and experts. This boot also features adjustable flex screws on the spine, allowing you to stiffen or soften the flex to your liking. The Editors' Choice-winning Rossignol Pure Pro Heat has this feature as well, and it's a thoughtful addition that we appreciate.
We skied all kinds of terrain with confidence in these boots. We loved skiing both steep off-piste runs and groomed cruisers in these boots. Overall, the RX 110 LV is a great boot, packed with performance and, now, comfort.
Comfort and Fit
This year we tried out the LV, or low volume, version of the RX. This measures slightly narrower than the other low volume boots in our test at 97mm. The Tecnica Mach1 has the second smallest width in our test at 98mm. This measurement is often called a boot's last.
When we tested the previous version of this boot, several testers noticed their feet falling asleep throughout the day. Some even had to open their buckles when riding the lifts or gondola to provide some relief. We don't believe in the mantra no pain, no gain when it comes to high-performance ski boots. Thankfully this new version made comfort a much bigger priority. We used to talk ourselves into sacrificing comfort for performance, but those days are gone. We are armed with more knowledge than ever about how to find a comfortable boot without sacrificing our skiing.
The new RX 110 LV has the same precise heel pocket as the older model, hugging your Achilles and locking your heel into place. We love this. We also love what Lange is calling their New Shin Control thermo-formable liner. This smooth, luxurious tongue adapts perfectly to the lower leg. The claim is that it increases support while alleviating common pressure points and shin sensitivity, thus improving comfort and performance. Even if we don't understand exactly how Lange does it, it works, and that's a big deal.
We're not into making judgments on personal style. Maybe you like to wear flashy colors or faux fur. Maybe you're into Gortex and super techy outerwear. We salute all of you, for being you! And every boot, no matter its look, has it's own personality too.
Some people might call what Lange has done with this boot understated, but we like it. Its reminiscent of race-inspired no frills boots, but hides a little secret. It's got frills. There's plenty of innovation in this boot, although it's not immediately obvious. Lange's unique women-specific liner is made of 100 percent thermo-formable dual-density foams. This means you can take and bake it at your local shop. It has thicker denser foam in places that need more padding and thinner foam where you don't.
One of the most interesting features is the anatomical asymmetric tongue. It helps distribute shin pressure evenly, because we're not just flexing forward, we're continually pressing diagonally against the tongue.
Another handy feature is the dual density heel and toe pieces. They give you traction and minimize the usual teeth chattering thunk that comes with walking in ski boots. The buckles are micro-adjustable, as most are. What's noteworthy about them, is that their sleek shape and indentation makes them easy to grab.
The RX 110 LV is a beefcake boot disguised in a sleek package. The power strap is substantial, although only advertised as 35mm, it seems as wide to us as the Rossignol Pure Pro Heat, which is listed as 40mm. It is also wider than the Tecnica Mach1, which is allegedly the same width.
The replaceable heel and toe pieces are our favorite in the test. The soft, dense, shock-absorbing dense rubber combined with a harder plastic makes for very easy for walking, even when we had to park far away from the lifts on a powder day.
The new and improved RX 110 LV is notably warmer than her predecessor. Using THINSULATE, which is lightweight synthetic insulation, these boots keep you warm and dry. We hypothesized that the newfound warmth might be partially due to the new pre-shaped liners. Instead of insulating a torpedo-shaped sock that mildly resembles a foot, Lange took the time to cut their liner perfectly, to precisely mirror the plastic shell of the boot. This means the liner gives you more space where you need it (like your forefoot and your toes) to help maintain blood flow and circulation.
This most certainly wasn't as warm as the Rossignol Pure Pro Heat or the Salomon X Pro 90, but these boots both feature integrated heating. You can always add an aftermarket heating system to any boot if you love the way it skis and want your feet warmer on cold days.
In our opinion, the newer RX 110 LV appeals to a much larger range of women, not just the ex-racers and experts. This boot can do it all for the intermediate through advanced skier, with the caveat that it's a little soft for our heavier and taller framed testers or anyone who would rate themselves as an expert.
This model performs like a twin sister to the Nordica Speedmachine 105 even with the 110 flex rating. The Lange RX 110 has a shorter cuff than the Speedmachine, making it a better fit for most shorter and smaller framed skiers.
Lange has long upheld their reputation for delivering a product that delivers precision and performance. It seems that they've outdone themselves and blended these traits with comfort. The RX 110 LV retails for $600. This places it in the median range for cost. The Nordica Speedmachine 105 offers a better value though, as it performs almost identically to the Lange and only retails for $500. We still consider the RV 110 a good value. If it meets all your criteria, give it a try, we think you'll like it as much as we did.
This is a truly an all mountain boot in a race-inspired chassis, and Lange managed to make it comfortable. If you've skied this boot in the past, we caution that it is less stiff than the older version. It does feel softer than what we'd expect from a 110 flex. If you have a narrow foot, this LV model makes for a much closer fit. Fortunately, the plastic shell is thick and pliable, allowing your boot fitter to deliver you the very best custom fit.
